Vodacom is not longer the best service provider

Hi i am extremely unhappy with Vodacom and the lack of service offered from them

I current have two complaints :

1. the fact that Vodacom no longer confirms the amount of time left on your call prior to your airtime run out .

2. The expensive call rates.

I have reach my boiling point, so far everytime I've been on a call with customers or personal phone calls my line just switches off without letting my know that i am about to reach my call limit. IT WORKED IN THE PAST, I DON'T UNDERSTAND WHY IT IS NO LONGER WORKING. I called the call center and was informed that this notification service is only valid for customers that buy voice minutes( what stupid thing is this) airtime services the exact same purpose as buying voice minutes.I have also been informed by a manager that Vodacom conducted a service to find out if people were happy with the fact that they would no longer be receiving notifications prior to their airtime running out: Question who are the people you asked and what percentage of these people buy airtime and are on contract? You want to waste peoples time by getting them to stop there day to BUY VOICE MINUTES, THIS IS RIDICULOUS. VODACOM 'USE" TO BE THE TOP SERVICE PROVIDE IN SOUTH AFRICA with there network coverage, airtime, reliability but .............it is unfortunate that they are no longer the best services provider. , WHICH MAKES SENSE WHY THEY "USE TO " . in my opinion Vodacom sucks, they expensive and i wish i never took out a contract which i'm bounded to for 24 months. I want someone to call me that can actual make a difference to the fact that i want a notification prior to my airtime running out. If you cannot fix this don't bother wasting your time.
